What is the function of the phospholipid bilayer of the cell membrane?

• allows large molecules to pass through the cell membrane

• allows small, non-polar molecules to pass through the cell membrane

• identifies the cell and allow for cell-to-cell communication

• stabilizes the fluidity of the cell membrane

What is the function of the transport and channel proteins of the cell membrane?

• allows large molecules to pass through the cell membrane

• allows small, non-polar molecules to pass through the cell membrane

• identifies the cell and allow for cell-to-cell communication

• stabilizes the fluidity of the cell membrane

What is the definition of Selective Permeability?

• The movement of materials across the cell membrane that requires NO ENERGY from the cell.
  

• The movement of materials through (or across) the cell membrane
  

• The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.

• The movement of molecules from an area of high concentration to a area of low concentration
